(-Cl. 30-34) This inventionrelates to shavers, and particularly to a shaver having an electricplug-in cord an integral part thereof.

' In electric shavers employed in the art, the shaver casing is providedwith a socket engageable with a mating plug on a cord furnished with theshaver. Oftentirnes the cord is misplaced and the shaver is then out ofservice until the cord is found or a new cord procured. The plugengagement with the socket in the casing becomes loose and it isdifiicult to maneuver the shaver and hold it in a manner to retain theplug within the socket. To overcome this and other difliou lties when aseparate cord is utilized, a way has been devised of maintaining thecord in fixed relation to the casing and winding it thereon when theshaver is not in use. The winding portion is such that when the cord isunwound the casing is retained within the usually provided dimensionsthrough the folding of fingers or the movement of a portion of thecasing thereinto so that the same feel will be had when grasping theshaver as when a separate cord is provided therefor. With thisarrangement, the cord is never separate from the shaver and nodiflFiculty is experienced when using the shaver because of theseparation of the plug from the provided socket.

A pair of L-shaped fingers may be pivoted on the rear end of the casing,recessed in slots in the rear end and the adjacent portions of the sidewalls of the casing so as not to interfere with the hand when graspingthe shaver when in use. After the shaver has been used, the L-shapedfingers are then swung backwardly in extension of the rear end, the onebranch being disposed parallel to the other and the longitudinal axis ofthe shaver and the other branch extending outwardly therefrom to providea winding space. The end plug of the cord may then be inserted in a pairof apertures between the L-shaped fingers and the cord in doublerelation may be wound into the winding space of the L-shaped fingers andwith the doubled over end tucked into the wound turns of the cord. Withsuch an arrangement, the cord is maintained in secured relation to thecasing and forms a neat unit package therewith.

-In another form of the invention, the rear end of the casing may beseparate therefrom or a separate end plate provided having slidingextensions thereon, such as four pins which permit the end wall to moveoutwardly and form a winding space for the cord. The end plug is securedbetween the various turns of the cord and maintained in unit compactrelation with the shaver casing. When the shaver is in use and the cordhas been unwound, the end plate may be moved inwardly on the four pinsto close the winding space in which the cord was wound to provide acompact casing when grasped by the operator.

In another form of the invention, the cord extending from the casing iswound about the side walls with a helical slot provided therealong whichprevents the wound loops from sliding along the casing. A recessedportion having apertures is provided in the casing in which the end plugof the cord is inserted for maintaining the cord wound upon the body ofthe shaver casing.

-In still another form, the end portion of the casing may be pivoted onthe axis of the shaver and provided with a winding space in which theend of the doubled cord may be secured and wound within the space byturning the end portion. The end plug on the cord is secured in anaperture in the casing and in the rotatable end portion for locking thelatter portion against rotation and retaining the cord within thewinding space.

Various other forms of the invention would be apparent to one skilled inthe art of shavers for winding the cord upon the casing or portionsapplied thereto when one of its ends is conductively joined to the motorthereof.

Accordingly, the main objects of the invention are: to provide a shaverhaving an electric cord secured to the shaver motor and wound on thecasing thereof in a manner so that when the cord is unwound the casingwill be smooth to the grasp of the operator; to provide a pair ofL-shaped fingers at the end of the shaver casing which may be movedoutwardly from a position along the side wall to form a winding spaceinto which the cord may be wound and secured when the conducting prongsof the plug on the end of the cord are inserted in apertures provided inthe casing between the fingers; to provide winding space upon the casingof the shaver onto which the cord fixed to the motor within the case maybe wound and secured against rotation through the use of the prongs ofthe .plug provided on the end of the cord, and, in general, to provide ashaver with an attached cord which is simple in construction, positivein operation and economical of manufacture.

Other objects and features of novelty of the invention will bespecifically pointed out or will become apparent when referring, for abetter understanding of the invention, to the following descriptiontaken in conjunction with the accompanying drawing, wherein:

FIGURE 1 is a plan view of a shaver embodying features of the presentinvention, with the cord broken therefrom;

FIG. 2. is a broken view of the structure illustrated in FIG. 1, withthe cord wound upon the hinged supporting elements thereof;

FIG. 3 is a sectional view of the structure illustrated in FIG. 2, takenon the line 3-3 thereof;

FIG. 4 is a view of structure, similar to that illustrated in FIG. 1,showing another form of the invention;

FIG. 5 is a sectional view of the structure illustrated in FIG. 4, takenon the line 55 thereof;

FIG. 6 is a view of structure, similar to that illustrated in FIG. 4,showing still another form of the invention;

FIG. 7 is a view of structure, similar to that illustrated in FIG. 3,showing another form which the invention may assume, and

'FIG. 8 is a broken sectional View of the structure illustrated in FIG.7, taken on the line 8-8 thereof.

Referring to FIGS. 1 to 3, a shaver it) is illustrated, having a casingll with a shaving head 12 at one end and a handhold portion 13 at theopposite end. A pair of L- shaped fingers 14 is secured on the handheldend of the casing by pivots 15 within slots 1d at the end and the sideportions thereof, as illustrated in FIG. 1. When so disposed, thehandhold portion of the casing is not interfered with in any manner bythe fingers 14. An electric cord 17, of conventional form, extendsthrough an aperture 18 in the casing from conducting relationship with amotor within the casing, which is not herein illustrated as it forms nopart of the present invention. A leaf spring 19 is secured within thecasing by suitable means, as illustrated more specifically in FIG. 3,having the end portions 21 disposed in engagement with the side 22 ofthe square end 23 of each finger 14 through which the pivot 15 extendswhen the fingers are extended upwardly to provide a winding space 24into which the cord 17 may be wound. When the fingers are disposed inthe recesses 16, the ends 21 of the leaf spring 119 will engage thefaces 25 of the square end portions 22 of the fingers 14 and will urgethe fingers into the slots and retain them therein during the time theshaver is being employed, with the cord unwound from the winding space24. The free end of cord has the usual plug 26 thereon which has theconducting prongs 27 extending from the end thereof. As clearlyillustrated in the figures, a pair of recesses 28 extends inwardly ofthe casing between the pivots on either side of the leaf spring 1%.These apertures are of a size to receive the prongs 27 of the plug 2 6so that after the winding operation the plug 2c is secured to the casingby the prongs to thereby anchor the free end of the cord and retain allof the turns within the recess 24. it may be desirable to Wind the corddoubled by inserting the prongs of the plug 26 into the apertures 23 andwind the cord from the end extending from the casing and from the plugtogether within the winding space 24- and tucking the doubled end of thecord into the turns wound within the winding space. This reducessubstantially the time required to Wind the cord within the windingspace or to unwind it from the space.

In FIGS. 4 and 5, a further form of the invention is illustrated, thatwherein a shaver 31 is of the conven tional form, having a shaving head32 and a butt end 33 which is engaged by the hand of the operator whenshaving. The butt end as herein illustrated is separate from the casing34, being secured thereto by suitable means, herein illustrated as byfour rods 35 which extend into apertures 36 formed on the wall of thecasing. The ends of the rods may be bent outwardly at 37 to slide Withina wider portion of the aperture so as to act as stop means to limit theextension of the butt end 33 from the casing 34-. This provides awinding area 38 into which the cord 17, which extends through the wallof the casing as above described, is wound about the four pins 35 andretained in position when the plug 26 is nested within the turns of thecord. It is within the purview of the invention to maintain the buttportion 33 in fixed position with the casing 34 and have a platerecessed therein and supported on the four pins 35 so that the plate maybe moved outwardly from the butt end 33 to form the Winding recess 33.

In FIG. 6, a still further form of the invention is illustrated, thatwherein a shaver 41 has an elongated casing 42 containing a threadli'kerecess 43 on the outer surface in which the cord 17 may be wound andsecured therein when the plug 26 is retained in an angularly disposedrecess 44 in the side Wall of the casing. Such an arrangement ispossible where the prongs 27 of the plug 26 span the operating shaft ofthe motor which drives the mechanism to operate the head 45 of theshaver.

In FIGS. 7 and 8, a still further form of the invention is illustrated,that wherein a rotatable Winding element 51 is mounted on the end 5 2 ofthe shaver casing. This mounting is effected by having an enlargedcircular head portion 53 on the element secured within a circular recess54 of the casing. With this arrangement, the cord is double and thedoubled end 55 is secured Within a slot 56 in the center of theoval-shaped portion 57 about which the cord is wound. After the element51 has been rotated to wind up the cord, the end plug '26 is insertedthrough an aperture 58 at either elongated end of the outer portion ofthe element '51, with a prong 27 thereof extending into a slot 59 in thebutt end of the casing 52 to retain the end of the cord fixed to thecasing and the element 51 from rotating. It will be noted in thisarrangement that one of the prongs 27 is disposed outside of the casingand only one slot 59 provided at each side of the casing for receiving aprong '27 for locking the rotatable element on the casing.

While, as pointed out hereinabove, various other arrangements may beprovided for securing the cord permanently attached to the shaver, it isto be understood that the basic novelty of the invention is to providemeans for storing the cord on the shaver casing in a compact manner andin unit relation therewith. T he arrangement is such that when the cordis unwound to permit the shaver to be employed, no discomfort will befelt from the hand grip portion of the casing on which the wire wasWound. In all of the arrangements herein illustrated, are provided fortaking care of the plug at the end of the cord before or after windingthrough the employment of suitable apertures within the casing intowhich the terminals of the plug are inserted.
